[0026] Here, exemplary embodiments will be described in detail, and the embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present utility model. Instead, they are only examples of devices consistent with some aspects of the present utility model as detailed in the attached claims.

[0027] The combined nested LCP cabinet of the utility model, which is easy to disassemble and assemble, is installed by combining and nesting the nested installation components in the LCP cabinet body, such as Figure 1 As shown, the combined nested LCP cabinet of the utility model includes an LCP cabinet body 1, a nested installation component 2 and an installation component support rail 3; wherein, the LCP cabinet body 1 includes an LCP cabinet body shell 11, an LCP cabinet body rear door 12, an LCP cabinet body vertical beam 13, and a vertical beam square hole 14; the nested installation component 2 includes a device mounting plate 23, a right side mounting plate 21, a left side mounting plate 22, a fixing plate 24, a fixing plate mounting hole 25, a hoisting hole 26, an array hole 27 and a long strip hole 28; the nested installation component 2 is used to install components and wiring, etc., the LCP cabinet body 1 is used to place the installed nested installation component 2, the installation component support rail 3 is used to push the installed nested installation component 2 into the LCP cabinet body, and the installation component support rail 3 is detachable.

[0028] When installing the combined nested LCP cabinet that is easy to disassemble and assemble provided by the utility model, first fix the installation component support slide rail 3 to the bottom of the LCP cabinet body, then install the nested installation component 2, and use the overhead crane to lift the installed nested installation component 2 to the installation component support slide rail 3, and then use the slide rail to push the nested installation component 2 into the LCP cabinet body, and then remove the installation component support slide rail 3 and install the LCP cabinet rear door 12, thereby completing the installation of the entire combined nested LCP cabinet. It should be noted that if it is necessary to inspect and repair the various components and cables in the LCP cabinet at a later stage, it is only necessary to open the front door of the LCP cabinet body 1 for inspection and repair. Opening the front door of the LCP cabinet body 1 can realize the inspection and repair of components and cables, and there is no need to remove the nested installation component 2 from the LCP cabinet body 1. Therefore, the utility model is provided with a detachable installation component support slide rail 3. After the assembled nested installation component 2 is moved to the inside of the LCP cabinet body 1, the installation component support slide rail 3 can be removed.

[0029] The installation position of the detachable mounting assembly support rail 13 can be determined according to the height of the nested mounting assembly 2, the installation height and the size of the LCP cabinet rear door 12 to ensure that the mounting assembly support rail 13 can be easily removed after the nested mounting assembly 2 is installed; Figure 2 As shown, the detachable installation component support rail 3 is installed at the bottom of the LCP cabinet vertical beam 13 in the LCP cabinet 1. The installation component support rail 3 is symmetrically arranged in the LCP cabinet 1, and is used to push the assembled nested installation component 2 into the LCP cabinet. The slide groove of the installation component support rail 3 is provided with a reinforcing rib structure to increase the load-bearing capacity of the installation component support rail 3 and avoid damage to the structure of the nested installation component 2 due to the excessive weight of the nested installation component 2.

[0030] Unfold and splice the three mounting plates in the nested mounting component 2, namely the right mounting plate 21, the left mounting plate 22, and the device mounting plate 23, in a "T" shape as shown. It should be noted that at this time, the three mounting plates have no connection relationship, but are only unfolded according to the "T" structure and fixed on the operating table respectively. However, before fixing, it is necessary to determine the positions of the three mounting plates fixed on the operating table according to their final positions in the LCP cabinet, the mounting positions of the components, and the wiring positions. The device installation and wiring work are carried out on the mounting plates in the "T" shape structure. The three mounting plates in the assembled nested mounting component 2 are in a "凵" shape structure. When the unfolded mounting plates are used for device installation and wiring work, there is a large operating space, which can meet the needs of multiple people for simultaneous installation and wiring, thus improving the installation efficiency of the nested mounting component 2; as Figure 3 shown Figure 4As shown, the device mounting plate 23 is also provided with array holes 27 and long strip holes 28. The array holes 27 are symmetrically arranged on both sides of the device mounting plate 23, and the distances between the array holes 27 are equal, which are used to adjust the mounting height of the device mounting plate 23, facilitating the adjustment of the tightness of the wire harness and the layout of other devices; long strip holes 28 are provided at the joints of the right mounting plate 21 and the left mounting plate 22 in the nested mounting assembly 2 and the device mounting plate 23. The long strip holes 28 are used to adjust the distance between the right mounting plate 21 and the left mounting plate 22 after installation. When installing the nested mounting assembly 2, the left mounting plate 22 and the right mounting plate 21 are installed in the minimum distance manner according to the long strip holes 28, avoiding the situation of collision and friction when the nested mounting assembly 2 is pushed into the LCP cabinet body 1, facilitating the pushing of the assembled nested mounting assembly 2 into the LCP cabinet body 1. After the nested mounting assembly 2 in the shape of a "凵" is pushed into the LCP cabinet body 1, the distance between the left mounting plate 22 and the right mounting plate 21 is adjusted through the long strip holes 28, making the distance between the left mounting plate 22 and the right mounting plate 21 the largest in the LCP cabinet body 1, that is, the two side mounting plates are closely attached to the inner wall of the LCP cabinet shell 11, making the structure between the components in the LCP cabinet body 1 more compact and facilitating the better fixation of the nested mounting assembly 2 and the side beam of the LCP cabinet vertical beam 13 with bolts; hoisting holes 26 are provided at the tops of the right mounting plate 21 and the left mounting plate 22, which are used for the overhead crane to hoist the assembled nested mounting assembly 2. The nested mounting assembly 2 is hoisted to the mounting assembly support slide rail 3 through the hoisting holes 26, solving the problem that the nested mounting assembly 2 is too heavy and inconvenient to move. At the same time, hoisting by the overhead crane is safer, avoiding potential safety hazards that may occur during manual movement; fixing plate mounting holes 26 are also provided on the right mounting plate 21 and the left mounting plate 22, which are used to install the fixing plate 24 to fix the nested mounting assembly 2. After the nested mounting assembly 2 is assembled, the nested mounting assembly 2 is in the shape of a "凵" character structure, and this structure is unstable and may cause the deformation of the mounting plate structure during hoisting. Therefore, the fixing plate 24 is fixedly installed at the position of the fixing plate mounting holes 26 with bolts. At this time, the nested mounting assembly 2 is in the shape of a "口" character structure, making the nested mounting assembly 2 more firmly structured and avoiding the adverse impact on the overall performance of the LCP cabinet due to structural deformation during hoisting. Then, the assembled nested mounting assembly 2 is hoisted onto the mounting assembly support slide rail 3 by the overhead crane, and after the nested mounting assembly 2 is pushed into the LCP cabinet body 1 through the mounting assembly support slide rail 3, the fixing plate 24 is removed; the guide rail and the wire groove are arranged on the two side mounting plates. The guide rail is used to install the terminal block, and the wire groove is used to place the wire harness sorted out after wiring in the LCP cabinet, avoiding the situation of messy internal structure and inconvenient assembly caused by complex routes and numerous cables.

[0031] Example 1

[0032] When installing the mounting component support slide rail 3, the installation position of the detachable mounting component support slide rail 3 can be determined according to the height of the mounting plate in the nested mounting component 2, the installation height, and the size of the rear door 12 of the LCP cabinet body. In this embodiment, it is detachably installed at the bottom of the LCP cabinet vertical beam 13 in the LCP cabinet body 1, as Figure 2 shown. The mounting component support slide rail 3 further includes a chute, and the chute is provided with a rib structure to prevent damage to the structures of the nested mounting component 2 and the mounting component support slide rail 3 caused by the overweight of the nested mounting component 2. Specifically, the mounting component support slide rail 3 is fixed to the LCP cabinet vertical beam 13 with four M6×12 bolts. Preferably, the LCP cabinet vertical beam 13 is provided with a vertical beam square hole 14 with a size of 9×9, and a snap nut is also provided on the vertical beam square hole 14 to facilitate the installation and disassembly of the mounting component support slide rail 3.

[0033] When assembling the nested mounting component 2 in this embodiment, as Figure 3 shown, the three-sided mounting plates in the LCP cabinet body 1 are unfolded in a "T" shape on the out-of-cabinet operation platform. The device mounting plate 23 is located in the middle position, the right mounting plate 21 is located on the right side of the device mounting plate 23, and the left mounting plate 22 is located on the left side of the device mounting plate 23. At this time, multiple people can simultaneously install electronic components, guide rails, wire grooves, and perform wiring and cabling work on the three-sided mounting plates. The three-sided mounting plates are of an adjustable connection structure, which can not only meet the needs of multiple people to install devices and perform wiring and cabling simultaneously, but also effectively solve the problems of high difficulty and low efficiency in device installation and wiring and cabling caused by the narrow space and dim light inside the cabinet. After the device installation and wiring and cabling work are completed, the three-sided mounting plates are spliced and installed in a "U" shape. Specifically, as Figure 4 shown, the device mounting plate 23 is provided with array holes 27 and long strip holes 28. The array holes 27 are symmetrically arranged on both sides of the device mounting plate 23, and the distances between the array holes 27 are equal, which can adjust the installation height of the device mounting plate 23, as well as adjust the tightness of the wire harness and the layout of other devices. Long strip holes 28 are provided at the connections between the right mounting plate 21 and the left mounting plate 22 and the device mounting plate 23. The long strip holes 28 are used to adjust the distance between the right mounting plate 21 and the left mounting plate 22 after installation. When installing the nested mounting component 2, the left mounting plate 22 and the right mounting plate 21 are installed in the minimum distance manner according to the long strip holes 28. In this embodiment, the two side mounting plates are mainly used to arrange the wiring of a large number of terminal blocks and wire grooves, and most of the control components are installed on the device mounting plate 23 located in the middle position, but control components can also be installed on the two side mounting plates.

[0034] After the nested installation component 2 is assembled, the fixing plate 24 is installed through the fixing plate mounting holes 25 set on the right mounting plate 21 and the left mounting plate 22 to fix the assembled nested installation component 2. The nested installation component 2 and the fixing plate 24 are fixed and installed by bolts. Preferably, in this embodiment, two fixing plates are selected to fix the nested installation component 2, which are respectively arranged at the top and bottom of the two side mounting plates close to the front door of the LCP cabinet 1; then, through the lifting holes 26 set on the top of the right mounting plate 21 and the left mounting plate 22, the nested installation component 2 is lifted by a crane to the installation component support slide rail 3 installed at the bottom of the LCP cabinet vertical beam 13, and the assembled nested installation component 2 is pushed into the LCP cabinet 1 by the installation component support slide rail 3, and then the installation component support slide rail 3 is removed.

[0035] After the assembled nested installation component 2 is pushed into the LCP cabinet 1, the fixing plate 24 near the front door side of the LCP cabinet 1 is removed. At this time, the distance between the left installation plate 22 and the right installation plate 21 is the smallest. Then, the distance between the left installation plate 22 and the right installation plate 21 is adjusted through the long holes 28 so that the distance between the left installation plate 22 and the right installation plate 21 is maximized in the LCP cabinet 1, that is, the right installation plate 21 is closely attached to the right inner wall of the LCP cabinet shell 11, and the left installation plate 22 is closely attached to the left inner wall of the LCP cabinet shell 11, so that the internal structure of the installed LCP cabinet 1 is compact.

[0036] The above description is only a specific embodiment of the present invention, so that those skilled in the art can understand or implement the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.

[0037] It should be understood that the present invention is not limited to the above-described contents, and various modifications and changes can be made without departing from its scope. The scope of the present invention is limited only by the appended claims.
